Answer:
40%
Step-by-step explanation:
Number of girls = 7
Number of boys = 13
Total students = 7 girls + 13 boys
= 20 students
Running club
Number of girls = 5
Number of boys = 3
Total students in the running club = 5 girls + 3 boys
= 8 students
percentage of the students that are in the Running club = Total students in the running club / Total students
× 100
= 8/20 × 100
= 0.4 × 100
= 40%
Percentage of the students
at this Private School are in the Running club is 40%

Review the diagram.
On a coordinate plane, a vector labeled 120 meters forms angle 25 degrees with the x-axis. It goes to point mirror 1. Another vector labeled 90 meters goes from point mirror 1 to mirror 2. It forms angle 20 degrees with a horizontal line. Point mirror 2 goes to (0, 0).
A laser beam is aimed 25° from horizontal at a mirror 120 m away. The beam bounces off the mirror and continues for an additional 90 m at 20° above horizontal until it hits a target, mirror 2. What is the distance between the origination point and the target?
approximately 85 m
approximately 122 m
approximately 174 m
approximately 194 m
Answer:
Approximately 85 m
Step-by-step explanation:
Let x represent the distance between the origination point and the target
Distance between original point and mirror 1 = 120 m
Distance between mirror 1 and mirror 2 = 90 m
The measure of angle Opposite the distance between the origination point and the target = 20 + 25 = 45°
Use Cosine rule to find x as shown below:
Use The Law of Cosines to find side a first:
[tex] a^2 = b^2 + c^2 - 2bc \times Cos(A) [/tex]
Where,
a = x
b = 90 m
c = 120 m
A = 45°
Plug in the values
[tex] x^2 = 90^2 + 120^2 - 2(90)(120) \times Cos(45) [/tex]
[tex] x^2 = 22,500 - 21,600 \times Cos(45) [/tex]
[tex] x^2 = 22,500 - 15,273.5065 [/tex]
[tex] x^2 = 7,226.4935 [/tex]
Square both sides
[tex] x = \sqrt{7,226.4935} [/tex]
[tex] x = \sqrt{7,226.4935} [/tex]
x ≈ 85 m

What do the slope and y-intercept of a real-world linear function represent?
Answer:
Word problems with linear equations (that is, with straight-line models) almost always work this way: the slope is the rate of change, and the y-intercept is the starting value.

An employee's time at work increased from 32 hours per week to 40 hours per week. By what percentage did the
time at work per week increase?
Answer:
You have to take the ratio so you divide the new value on the old value and compare It with 100 so you write
(40)/(32)=(x)/(100)
And this means that x = 125
So the ratio of the increase of the new time is 125%
But the real increase is 125 - 100 = 25%
the length of a rectangle is 4 feet longer than its width.its area is 32 square feet.what are its dimensions?
Answer: Length=8, Width=4
Step-by-step explanation: I did this by trial and error, but you can also use an equation. The length is x+4, the width is x. Your equation would be x(x+4)=32. That is equal to x^2+4x=32. Solve this by completing the square. X^2+4x+ (4/2)^2=32+ (4/2)^2
X^2+4x+4=36. (X+2)(x+2)=36. X+2=6, x=4.

Find the length of side x in simplest radical form with a rational denominator
Answer:
The length of x=3/1
Step-by-step explanation:
Given the right triangle
Ф = 30
We know that
sin Ф = opposite/hypotenuse
The opposite of angle 30° = x
The hypotenuse is = 6
so
sin 30 = opposite/hypotenuse
1/2 = x/6 ∵ sin 30 = 1/2
1/2 × 6 = x
6/2 = x
3/1 = x
Therefore, the length of x=3/1
Forty-eight 6th graders bring their lunch to school. This is thirty percent of the 6th-grade class. How many students are in the 6th grade? (number only to the nearest whole)
Answer:
160 students in the 6th grade.
Step-by-step explanation:
There are 160 students in the 6th grade because if 48 students is 30 percent then 10 percent is 16. Meaning that 100 percent would be 160.
Students l Percent
--------------l-------------------
48 = l 30
16 = l 10
160 = l 160

What are the coordinates of the vertex of the graph of the absolute value function h(x) = 3|x + 5| + 2?
Answer:
(-5,2)
Step-by-step explanation:
h(x) = 3|x + 5| + 2 is an absolute value function in vertex form. Vertex form is f(x) = a | x - h | + k with a vertex at (h,k). So find h and k in the function, 3|x + 5| + 2, but remember in the formula h is negative so flip the sign of what ever is in your function. So if h=-5 and k=2, then the vertex is (-5,2).

6 - 2/3 (x+5) = 4x solve algebraically for the exact value of x
Answer:
x = 2
Step-by-step explanation:
1 - Rewrite
6 - 2/3 (x+5) = 4x
2 - Distribute
6 - 2/3x + 10/3 = 4x
3 - Combine like terms and get x alone
6 10/3 - 2/3x = 4x
+2/3x +2/3x
6 10/3 = 4 2/3x
------------------------------- Convert to decimals
6.3333333333.... = 4.333...x
-------------------------------- Divide both sides by 4.33...x
2 = x

Eight toy camels and three toy pigs cost Gary $85. Twelve toy camels cost Sherry $96. Assuming everyone bought their toys at the same store and there were no discounts, what is the cost of two toy pigs?
Answer:
2 toy pigs cost $14
Step-by-step explanation:
If 12 toy camels cost $96, I can solve ($96 / 12 = $8) to find the price of 1 toy camel. Now, I know that 1 toy camel costs $8.
If 8 toy camels and 3 toy pigs cost $85, I can multiply the price of 1 toy camel by 8 and solve ($8 x 8 = $64).
Next, I can subtract Gary's total cost by the toy camels to find how much was spent on 3 toy pigs. ($85 - $64 = $21) Therefore, 3 toy pigs cost $21.
Then, I can solve ($21 / 3 = $7) to find the price of 1 toy pig. Finally, I can multiply ($7 x 2 = $14) to find that 2 toy pigs cost $14.
Answer:
Two toy pigs cost $14.
Step-by-step explanation:
Gary bought 8 toy camels and 3 toy pigs for $85.
Sherry bought 12 toy camels for $96.
Thus, each toy camel cost $96/12=$8
Now we know Gary spent 8*$8= $64 in toy camels.
The rest of the $85, $85 - $64 = $21 was spent on the 3 toy pigs, thus each toy pig cost $21/3=$7
If one toy pig costs $7, two toy pigs cost $14.
